7 Hodgkin Disease

69

 

 

7.7.2 Chemistry

Serum copper high (differential diagnosis: estrogen induced by contraceptive medication) and serum ferritin high

7.7.3 Immunological Analyses

Immune response decreased

Decreased mitogen-induced T-cell function

Hypersensitivity to T-suppressor cells

Increased risk of bacterial, fungal, or viral infections, especially after splenectomy

Herpes zoster virus infection in 35% of patients during or after irradiation therapy

In children with complete remission, disappearance of immunological deficits after treatment (in contrast to adults)

7.8Radiological Evaluation

7.8.1Chest

Evaluation by X-ray, computed tomography (CT), or positron emission tomography (PET) and Fluor-Deoxy-Glucose (FDG-PET); these are usually done in sequence but many centers now combine CT with PET scanning

Enlargement of mediastinal nodes in the anterior and middle mediastinum mostly

Posterior mediastinal enlargement usually together with retroperitoneal lymph node involvement

Lung tissue involvement (see above)

Manifestation of thoracic Hodgkin disease is often associated with nodular sclerosing histology

7.8.2Abdomen

Ultrasound, magnetic resonance imaging (MRI), and (FDG)- PET for documentation of abdominal involvement

Lymphangiography is rarely indicated and is contraindicated in patients with mediastinal involvement

Combination of venocavography and intravenous urography only indicated in unclear retroperitoneal involvement
